Multicast Management/Routed Behavior (No Change; Bpm And Group Qos With Outbound Acm/Vcm - Comtec CDM-840 Installation And Operation Manual

CDM-840 Remote Router
Appendix E
If required, you can create QoS rules with "Filter All" enabled to filter undesired Multicast from
traversing the satellite network for both the CTOG-250 and the CDM-840.
E.5.1

Multicast Management/Routed Behavior (No Change)

In both BPM and Router Modes, Multicast packets arriving at the Management (routed) port of
the CTOG-250 and CDM-840 must be configured to be transmitted to the WAN by adding a
Multicast-specific route table entry with a "/32" subnet.
Packets arriving at the CDM-840 downlink pass out the CDM-840 Ethernet Traffic port based
upon the following criteria (configurable via NetVue or the HTTP (Web Server) page for each
CDM-840):
• Downlink (outbound from the Hub Segment) Multicast All – All downlink outbound
Multicast packets pass to the Traffic LAN interface of the CDM-840 unit.
•
Use IGMP (Internet Group Management Protocol) – Only remotes that have IGMP clients
enabled with the Multicast address pass the Multicast packet to the CDM-840's LAN port.

ACM/VCM on the Outbound Carrier works with BPM by seamlessly matching packets to the
correct remote site. While no configuration is required, you have the ability to first use a VLAN
